Day 6 · Wed 4 NovHike day: the cliffs of Cala Domestica, and the Grotta Azzurra

Hike day, and everything is within 25 minutes of the bed. A loop over a mining saddle to Buggerru and back along wild cliff tops to a fjord-like cove, then the afternoon on the water under Pan di Zucchero if the sea and the boatmen allow.

Before you set off

  • Download the GPX for trail 301 “Anello Buggerru” (OpenStreetMap, exported via Waymarked Trails) into an offline app. The cliff-top section is only marked with cairns.
  • Long trousers (the maquis shreds bare legs), boots, 2 litres of water each, lunch. There’s no shade on the whole loop.
  • Message the Masua boat and SUP operators a few days ahead about a Grotta Azzurra / Pan di Zucchero trip this afternoon (numbers below). Expect a no: Freedome runs April–October only, and Warung Beach’s season ended on 31 Oct last year. Warung (+39 392 819 7964) is the best bet for a private trip.
  • Check the wind. A strong mistral (from the north-west) means no boats, and makes the cliff path unpleasant.

Step by step

  1. 08:30Drive

    Nebida → Cala Domestica

    14 km · 25 min
    SP83
    1. North on the SP83 through Masua, then up the winding inland stretch towards Buggerru: good asphalt, cliff drops.
    2. Turn left at the signed Cala Domestica turn and drive 1.2 km down to the car park.
    Cala Domestica car park Check on the day

    The main surface car park, with a second one just east (39.37150, 8.38328). €5 in summer; a visitor found it free in April, so it’s probably free in November. A boardwalk leads 250 m to the beach.

    Cost: Probably free in November

  2. 09:001Hike

    The Cala Domestica – Buggerru – Pranu Sartu loop (trail 301)

    A fjord-like cove between limestone cliffs, guarded by a Spanish tower. The loop goes inland on a well-marked mining track over a saddle to Buggerru, then comes back along the wild cliff tops past the Pranu Sartu mine and down into the hidden cove of La Caletta. You finish by walking through a short mine tunnel onto the beach.

    The loop, step by step (clockwise)

    Distance≈ 11.5 km
    Height≈ +500 m
    Time4 h 30–5 h
    GradeE, with an easy down-climb
    MarksRed-white “301” and blue CMSB
    1. 09:00From the car park, find the signpost “Cala Domestica” (39.37366, 8.38069). Take trail 301 / Cammino di Santa Barbara (red-white “301” and a blue tag with a yellow tower) inland up the small canyon, past the guidepost and stream crossings at 39.3703, 8.3857.
    2. 09:30Climb gently east (39.3670, 8.3954 → 39.3660, 8.3998) to a gate at 39.3684, 8.4046. Forestas calls this section “clear and well marked”.
    3. 10:00A rocky track climbs north to the Genna Arenas saddle (292 m, 39.37922, 8.40847), the high point of the day.
    4. 10:30Down the track north to the SP83 (vehicle barrier at 39.3870, 8.4050), then the path into Buggerru. Coffee and toilets in town.
    5. 11:15Leave Buggerru on the coastal track south by the Galleria Henry entrance (39.3966, 8.4003), then 39.3967, 8.3947 → 39.3914, 8.3917.
    6. 11:45Pranu Sartu: ruins of the mining village and a huge fenced open-pit mine. The Grotta Azzurra sea cave is in the cliffs below (by boat only).
    7. 12:00The cliff-top section, south at 80–110 m: a lunar plateau of white karst, with dry gullies (Su Zippiri) to cross. Only faded flags and many cairns: follow the GPX. Stay well back from the unfenced 50–100 m edges.
    8. 13:00The path comes down to Porto Casu / La Caletta by an easy down-climb along the rock (hands needed, polished limestone). If it’s wet, don’t: go back to Pranu Sartu and return on the inland track.
    9. 13:15Through the short mine tunnel (39.3750, 8.3795) onto Cala Domestica beach.
    Not a beginner path

    Reviewers say the cliff section is hard to follow and has sheer drops. It’s fine for fit, sure-footed hikers with a GPX. Turn back rather than improvise a line.

  3. 13:302Lunch

    Lunch and a swim at Cala Domestica

    The sea is still about 20 °C, and the cove is sheltered from everything except a strong westerly. The Oasi Beach bar behind the beach may be shut (its season dates couldn’t be confirmed), so bring your own lunch.

    Cala Domestica → Masua beach

    SP83
    1. Back up to the SP83 and south to Masua. The beach car park is at the bottom of the village.

    Paid in summer, probably free now. A second gravel car park is at 39.33343, 8.42181.

  5. 15:153Sea

    A boat to the sea caves, or Pan di Zucchero from the beach

    Only if an operator agrees to a private trip (unlikely in November): a 1 h 30 RIB trip round Pan di Zucchero (the 130 m sea stack), under Porto Flavia, and into the Grotta di Sardegna, the cave whose entrance seen from inside has the shape of Sardinia (Iglesias tourism treats it as the “Grotta Azzurra”). Or a guided SUP to Porto Flavia. Only in calm sea, and only with a guide in November.

    If nothing runs: sit on Masua beach (39.33328, 8.41978) right under Pan di Zucchero, or walk the coastal path south towards Nebida for an hour and back.

    Sunset

    Back to the Nebida belvedere for a second sunset (≈ 17:22, 10 min from Masua), or watch it from Masua beach behind Pan di Zucchero. The Spanish tower above Cala Domestica is no longer a good option: its path (307) is overgrown.

If things change

Shorter or easier
  • Short loop, ≈ 7 km, +400 m (the CAI version): walk the inland track to Pranu Sartu, the cliffs back to Porto Casu, then the tunnel. It skips Buggerru.
  • Easy: the Cammino di Santa Barbara path from Nebida to Masua (≈ 6 km one way, path 307: belvedere → Porto Banda → Masua, about 2 h). Walk out and back, or as far as you like.
If the cliff path is too much

From Pranu Sartu, go back the way you came (via Buggerru and the Genna Arenas saddle). It’s all marked trail, about 2 h back to the car.

If it rains

The caves are out: Su Mannau closes from the end of October, and Is Zuddas has no visits on Wednesdays from 2 Nov (weekends only). Instead, a guided tour of the Montevecchio mine (50 min; book on +39 338 459 2082, 10:00–13:00 and 15:30–18:30). Do Porto Flavia today if you missed it, and coffee in Iglesias old town.
